How to Solve Fogging Inside the Car?

[NathanMarie]

There are several methods to deal with fogging inside the car, which are: 1. When the fogging is not severe, you can appropriately open both windows to allow air convection. 2. Turn on the air conditioning cold air, which can eliminate fogging in a very short time. 3. Turn on the air conditioning cold and hot air, which can fundamentally solve the problem of glass fogging. 4. Use anti-fog spray, spraying a layer on the windshield to form an effective protective film, thereby preventing the condensation of water vapor. Here are some additional introductions: For some high-end brands, vehicles are equipped with functions to prevent fogging. The air conditioning system in these models constantly monitors the temperature and humidity inside the car and analyzes the critical temperature for water vapor condensation at the moment based on these two indicators. By comparison, it can determine whether the air inside the car will fog up on the front windshield.

The most common time I encounter window fogging is during my commute, especially on rainy or cloudy days when there's a significant temperature difference between the inside and outside of the car, combined with the moisture from breathing, which causes the windows to blur. The solution is simple: immediately turn on the air conditioning, set it directly to the mode that blows air onto the front windshield, and increase the fan speed. Within seconds, you can see the fog disappear. Using the recirculation mode can make the fogging worse, so I always start with the fresh air mode to ventilate. Another emergency method is to use the windshield wipers, but that's for external fog; for internal fog, I usually keep a defogging spray handy and occasionally spray a layer, which provides long-lasting anti-fog effects. To prevent fogging, I make it a habit to dry my wet shoes before getting in the car and avoid eating or drinking inside to reduce moisture. These methods are all very practical and take just a few minutes to implement, ensuring a safe and stress-free drive.

As someone who frequently drives to pick up and drop off my kids, window fogging is the most frustrating issue because the blurred vision is too dangerous. I've found that the quickest solution is to turn on the air conditioning's dehumidification function, set the temperature a bit higher, and blast it directly at the windshield—the fog disappears immediately. If the AC isn't effective, opening two windows for a few minutes to ventilate usually solves the problem. Prevention is key: every time I park, I check the car to ensure no wet towels or rain gear are left inside, and I regularly clean the windows because dust can cause fogging to occur more frequently. On rainy days, extra caution is needed—starting the car early to preheat with the fan helps maintain dryness. These practices have made traveling with my child much safer and more reassuring. Safety always comes first.

Driving to work with fogged-up windows is really annoying, especially on cold mornings. I usually turn on the air conditioner at full blast to defrost the windshield quickly. If the AC isn't working, cracking the window for ventilation helps. For daily prevention, keep the windows clean, avoid using recirculation mode too much, and opt for fresh air intake instead. Check if the air filter is clogged, as it can affect ventilation. For external fog, just use the windshield wipers. Remember not to panic—make sure everything's clear before hitting the road.
